Product Overview
Our heat seal lidding film (also known as sealing membrane or cover foil) is precision die-cut and designed to provide reliable, hermetic sealing for a wide range of rigid containers. It is widely used in the food and beverage industry to seal:
- Yogurt cups & dairy desserts
- Pudding & custard pots
- Sauce cups (ketchup, mayonnaise, dressings)
- Pet food trays (wet pet food)
- Drink cups & beverage containers
With full customization options – from material structure to shape, printing, and embossing – we deliver a ready-to-seal film that enhances product freshness, shelf appeal, and consumer convenience.
Two Functional Types: Easy Peel vs. Drink-Through
| Type | Feature | Best for |
|---|---|---|
| Easy Peel | Low peel force, smooth and clean opening without tearing | Products where consumers remove the entire lid to access the content (e.g., pudding, sauce, pet food) |
| Drink-Through (Standard) | Stronger seal, allows straw insertion directly through the film | Beverages, yogurt drinks, or any product consumed with a straw while the lid stays on |
Both types are engineered for consistent sealing performance on your filling line.
Up to 10-Color Printing – Vibrant Branding
Enhance your packaging with high-definition gravure or flexo printing. We offer:
Up to 10 colors – sharp, vivid, and fade-resistant
High-gloss finish that makes logos, nutritional information, or promotional graphics stand out
Custom designs to elevate brand recognition on the shelf
Printing is applied on the top surface; the sealing layer remains clean and functional.
Sealing Layer Customized to Your Container Material
The lidding film's heat-seal coating is matched to your specific container material for optimal bond strength. Compatible with:
PP (polypropylene) – most common for yogurt cups
PE (polyethylene) – used for flexible trays and bottles
PET (polyethylene terephthalate) – clear containers and rigid trays
Tell us your container resin type and we will supply the correct sealing formulation.
